This paper draws on an anthropological perspective on social security to explore the complex ways in which Czech- and Slovak-speaking migrants living in Glasgow negotiated their healthcare concerns and built security in the city and beyond. It is based on 12 months of ethnographic research conducted in 2012 with migrants who moved to Glasgow after 2004. Inquiring into healthcare issues and the re-sulting insecurities from the migrants’ perspective and in their everyday lives, the paper demonstrates how these issues were largely informed by migrants’ experiences of ‘uncaring care’ in Glasgow, rather than due to their lack of knowledge or understanding of the Scottish/UK health system. Furthermore, the findings reveal how these migrants drew on multiple resources and forms of support and care – both locally and transnationally – in order to mitigate and overcome their health problems. At the same time, the analysis also highlights constraints and limitations to the actors’ care negotiations, thus going be-yond a functional approach to social security, which tends to overlook instances of ‘unsuccessful’ or unrealised care arrangements. In conclusion, I propose that migrants’ care negotiations can be best understood as an ongoing process of exploring potentialities of care by actively and creatively opening up, probing, rearranging and trying out sources of support and care in their efforts to deal with per-ceived risks and insecurities in their everyday lives.

In the paper, the author analyses a model of a ring pack motion on an oil film. The local thickness of the oil film can be compared to the height of the combined surface roughness of a cylinder liner and piston rings. Equations describing the mixed lubrication problem based on the empirical mathematical model formulated in works by Patir, Cheng [6, 7] and Greenwood, Tripp [3] have been combined [13] and used in this paper. A model of a gas flow through the labyrinth seal of piston rings has been developed [14,16]. In addition, models of ring twist effects and axial ring motion in piston grooves have been applied [15,16].

In contrast to the previous papers of the author, an experimental verification of the main parts of developed mathematical model and software has been presented. A relatively good compatibility between the experimental measurements and calculated results has been achieved.

Father Marceli Dziurzyński (1861–1945) was a noted publisher and editor of a number of magazines, mainly for the country people. The most successful of them was Nowy Dzwonek (The New Hand Bell) that appeared continually from 1892, under altered names and at various intervals, until 1932. This article surveys the first phase of its history and its thematic range (religion, Polish history, current events in Poland and abroad, stories and poems). In that period the magazine also carried a number of supplements.
